To all whom t may concern.-

Be it known that I, CHRISTIAN CARL Grzn, a subject of the Emperor of Germany, resid-` ing at Cthen, in the German Empire, have invented certain new and useful Improve!` ments in Water-Gages, of which the follow-` ing is a specication. 1

rlhis invention relates to improvements in the construction of leveling-instruments; and it has for its object to produce an instrument adapted to be folded or put up into a small compass and carried about on the person; andto this end the invention consists in the con-1 struction, arrangement, and combination of; the parts that constitute the instrument, and,l in combination therewith, of a supporting-staff and inclosing-tube, substantially as hereinaf-A ter fully described.

In the accompanying drawings, Figure 1 shows my improved leveling-instrument secured to its staff by a vertical sectional elevation, only a part of the staff. being shown. Fig. 2 is a vertical section through the longer axis of theinclosing-case, showing the arrangement of the parts of the leveling-instrument within said case. Fig. 3 is ahorizontaltrans verse section of Fig. 2 on line :v x. Fig. a is a detail view of one of the articulated braces, illustrating the mode of securing the standglasses thereto. Figs. 5 and 6 are a sectional and a plan view of thetripod adapted for connection with the staff, and Fig. 7 is an elevation showing the instrument set up for use.

In these drawings, P indicates the inclosing-case, of substantially elliptical form in cross-section, provided with a suitable cover, I?, (shown in part in dotted lines, Fig. 2,) thrown open, said cover or lid being suit-ably hinged or otherwise connected with the case, so as to be readily thrown open or removed therefrom. Vithin the case, at each end of its longer axis, is formed a pocket for the reception of the stand-glasses C C of the leveling-instrument, which is composed as follows: of the stand-glasses referred to,a tlexiblc,preferably rubber, tube, S, connecting the standglasses, an articulated brace rod or bar, D D E, a fastening pin or spindle, J, and a stati, I, which may be of any suitable form and material; but for convenience of carriage and use for a twofold purpose I employ a staff in the sections D D of the brace rod or bar, as more,

`plainly 'shown in Figs. l and 4, the brace-rod being composedof live sections,hinged or otherwise articulated together-namely, the outer sections, `D D, provided with the clamping or holding sleeves A A for the standiglasses, the sections D D, andthe intermediate section, E. By means of this construction the brace-rod may be folded into a compact form, and as the stand-glasses C are connected by means of a rubber tube theilatter alsoniay be arranged to occupy but a comparatively small space, as shown in Figs. 2 and 3. The glasses C are iuserted into the sleeves A ofthe extended bracerod, so that the ends ot' the rubber tube on one end of said glasses will lie within or project through the sleeves. In this mannerthe glasses will be held more securely in ,position than could well be done by adirect connection Vbetween them and theirsupporting-s1eeves,`jas it is obvious that thc rubber tube will form` an elastic packing around the end of the glasses, and hold them securely within the sleevesby frictional contact, and at the same time protect the glasses against breakage. The intermediate section, E, of the' brace-rod has a screw-threaded perforation; and .I is a spin' die or pin screwthreaded at one end and ter minating at its other end in atlaring collar or boss, j,that has an axial screw-threaded socket, Fig. l, for the reception of a clampingscrew, G, on which works a clamping-nut, K. rPhe end of this screw G is passed through the perwill be firmly held on the said spindle. Vhen the parts are thus arranged, the spindle is screwed into the upper end of the staff, or, as

shown in Figs. 1 and 7, in the handle portion roo z' of the cane I, that is provided with a suitable screw-threaded socket for'this purpose.'

In order to adapt this staff or the cane I to be erected into position, a tripod is applied thereto, which is constructed of a sleeve, L, which, when a cylindrical staff is` employed, may be made of corresponding form; but when a tapering cane is employed, as shown, said sleeve is made of such a taper as to fit the lower or ferruled end of such cane. The tapering sleeve has at its upper and lower ends a collar, O and O, respectively, through each of which passes'a binding-screw, s and s, for securing the sleeve to the cane. Below the collar O of the sleeve L are formed three slots, Z, in which are pivoted the legs M, as shown in Fig. 5. Ifdesired, thelegs M may be formed of sections connected substantially like the sections of the brace-rod; or lengthening-bars adapted for connection with the legs M may be employed. When the tripod issecured to the cane I and the support for the leveling devices erected in proper position, said devices are screwed to the' cane, as above set forth, and the apparatus will be ready for use, as shown in Fig. 7.

It will` be seen that the spindle J forms av pivot onwhich the stand-glasses may be rotated, and then secured in the desired position by the clamping-nut K. It will also be seen that when theinstrument is to be used in alocality where a scarcity of water exists or is feared the stand-glasses and their tubular 'connection may be filled with water and said glasses securely corkedup before reaching Having now described my invention, what I claim is- 1. In a leveling-instrument, the combination, with the stand or level glasses, of a flexible tubular connection. a brace-rod for supporting the glasses in the proper relation to each other, and a staff to which said rod is de-Y tachably secured, as described.

2. In a leveling-instrument, the combination, with the stand or level glasses, of a flexible tubular connection and an extensible bracerod for supporting the glasses in proper relation to each other, as described.

3. In a leveling-instrument, the combination, with the stand or level glasses, a flexible tubular connection therefor, and an extensible brace-rod having bearing-sleeves at its extremities, of a iiexible packer or gasket for the glasses, interposed between the latter and the bearing-sleeves of the brace-rod, for the purpose specified.

4. In a leveling-instrument, the combination, with the stand or level glasses, a iiexible tubular connection therefor, a brace-rod for holding the glasses in proper relation to each other, and a staff for supporting said glasses in proper position, of a pivotal connection between the brace-rod and staff, and a clamping device whereby said glasses are rotatably connected with and may be clamped to said staff, said parts being detachably connected together, as described, for the purpose specilied.

5. In a leveling-instrument, the combination, with the stand or level glasses, a iiexible tubular connection therefor, an extensible brace-rod to support said glasses in proper relation to each other, and a staff for supporting the brace-rod and glasses in an upright position, of a tripod secured to the staff, said parts being detachably connected with one another, as described, for the purpose specified.

6. A leveling-instrument consisting of stand or levelv glasses, a liexible tubular connection therefor, an extensible brace-rod for holding the glasses in proper relation to each other, a spindle and clamping device for securing the brace-rod to a staff, a tripod, said parts being constructed to be folded into compact form, and an inclosing-case, as described.

7. A leveling-instrument consisting of stand or level glasses, a iiexible tubular connection therefor, an extensible brace-rod for holding the glasses in proper relation to each other, a spindle and clamping device for securing the brace-rod to a staff, and a tripod, said parts being constructed to be folded in compact form, and, in combination therewith, ot' an inclosing-case having pockets for the stand or level glasses, and a chamber for containing the other parts of the instrument, substantially as described, for the purpose specified.

8. The combination, substantially as described, with the stand-glasses, their flexible connecting-tube, and the extensible brace-rod for holding said glasses in proper relation to each other, and provided at a point intermediate of its extremities with a perforation, of the spindle J, the screw G, and nut K, for the purpose specified.

9. rllhe combination, substantially as described, with the stand glasses, their flexible connecting-tube, and the extensible brace-rod for holding said glasses in proper relation to each other, and provided at a point interme- IOO IIO

diate of its extremities with a perforation, of

the spindle J, the screw G, nut K, and cane I, into which said spindle is screwed, for the purpose specified.

l0. The combination of the standor level glasses, their flexible connecting-tube, the extensible brace-rod to hold the glasses in proper relation to each other, the'spindle J, and the screw G and nut K, for securing the brace-rod to the spindle of the cane I, and a tripod consisting of a sleeve, legs hinged thereto, and binding-screws, said parts being arranged for co-operation substantially as and for thepurposes specified.'

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
